2001 Volvo V40 Engine problems

manager. Aug. 27, 2007: The car is having same issue: sudden shifting @ low speed & jerking on fwy speed. This is very dangerous to drive and I don't know when the car is going to stall middle of fwy. I told the dealer that the car symptons are very much like etm problem (recall) on other models. Aug. 29,2007: Dealer replaced another #3 ignition coil and spark plug. I don't know how many times I will have to go back to the dealer for repeat repair. The dealer didn't bother to check etm unit. So far, I am lucky that I haven't gotten accident. (Same dealer service my car since 2001)

driving approximately 45 mph. I had a bit of trouble restarting it - but it eventually restarted. I was very nervous the rest of the way to the day care, but I made it without it stalling. I was able to leave the day care and decided to get to work and have it towed to the dealership. It stalled again. After many tries and 30 minutes later it started and I made it to work. I had it towed to volvo. They found a power supply interruption code -ecm30 and replaced the mass airflow sensor. Picked up the car later that day and on my way home from work the check engine came on again. As I pulled into my driveway it started stalling again. Took it back to volvo on 6/28. They worked on it for 5 hours while I waited. They replaced the front oxygen sensor, still had problems, replaced the rear oxygen sensor, the light still came back on. Replaced both sensors again and loaded software. That seemed to do the trick. I haven't had that same problem again so far. But I am noticing that my v40 sometimes slows (rpms rev up to around 4,000) when accelerating. This was very dangerous because when I needed to accelerate into traffic, vehicle slowed down. When I read in the paper about other volvo models have similar occurrences, I wanted to make sure someone new of the same type of problem happening in the 2001 v40 wagon. Every repair was under warranty and did not cost me anything thank goodness. My warranty is up this week -sure hope this doesn't happen again.*Jb
